California Department of Fish and Game U.S. Fish and Wildlife Service Section 3.5. Biological Resources foraging on the adjacent North Parcel property (Wetlands and Water Resources 2005b). This species is primarily associated with freshwater perennial marsh dominated by cattails and/or bulrush and riparian scrub. These wetland habitats are present in the vicinity of the Project site including a perennial stock pond immediately adjacent to the site. As such, tricolored blackbirds probably use the site for foraging. The small cattail patches present in some of the deeper ditches and ravines on the site are likely too small to support tricolored blackbird nesting colonies. • The Project site supports extensive stands of Viola pedunculata, the host plant for the Callippe silverspot butterfly and occurs within the species’ known historic range (Wetlands and Water Resources 2005b). While there are no confirmed observations of Callippe silverspot butterfly on the Project Site, it is considered to have moderate potential to occur. • Short-eared owl nests and forages in a variety of wetland types. The closest recorded occurrence for this species is just outside of the Project vicinity (12 miles from the Project site) (California Natural Diversity Database 2007). The Project site may support this species. • Saltmarsh common yellowthroat has been documented to occur within the Project vicinity (Wetlands and Water Resources 2005b). • Special-status bat species, pallid bat and Townsend’s big-eared bat, are known to occur in the vicinity of the Project (California Natural Diversity Database 2007) and may forage on the Project site and use the barns onsite (associated with the Sears Point Ranch facilities) for roosting (Wetlands and Water Resources 2005b). • Suitable habitat for northwestern pond turtle is present in the perennial stock pond immediately adjacent to the Project site near Lakeville Highway (Wetlands and Water Resources 2005b). Other potentially suitable habitat onsite may occur in Tolay Creek. The following seveneleven special-status wildlife species have low potential to occur in the Project site due to the presence of limited to no suitable breeding habitat or because the Project site is outside of the species known range. • Peregrine falcon and Long-billed curlew - Long-billed curlew and peregrine falcon are known to forage in a variety of wetland community types. These species have not been documented in the Project vicinity (California Natural Diversity Database 2007) and would not nest on the Project site because of a lack of suitable nesting habitat (Wetlands and Water Resources 2005b). These species may occasionally forage on the Project site but would not be impacted by the Project. • Ferruginous hawk and Merlin - Ferruginous hawk and merlin do not nest in California and are potential winter visitors to the Project site. These species may occasionally forage on the Project site but would not be impacted by the Project. • Western snowy plover – No habitat for this species occurs on the Project site.

California Department of Fish and Game U.S. Fish and Wildlife Service Section 3.5. Biological Resources • California tiger salamander and Vernal pool fairy shrimp - According to Wetlands and Water Resources (2005b and 2007) during numerous field surveys and analysis of the Project site, conducted during 2005 and 2006, vernal pool fairy shrimp and California tiger salamander were determined to have little to no potential to occur in the watershed based on a lack of known regional occurrences or lack of discovery during site surveys. Given that the Action area is outside of the known range for vernal pool fairy shrimp, this species is not expected to occur on the Project site. California tiger salamander is known to occur in Sonoma County but the Project site is outside of the currently known distribution of this species. As reported by Wetlands and Waters Resources (2005b and 2007) this species was not observed onsite during numerous surveys conducted within the watershed and the site contains only limited potential breeding habitat. This species therefore has low to no potential to occur onsite. • Conservancy Fairy Shrimp – The site is outside of the species range. • California Freshwater Shrimp – These shrimp are expected to be extant in nearby streams but have not been found to occur in the project area (USFWS 1998). • California Least Tern - The northernmost population is located east of the Napa Marsh. • Northern Spotted Owl - No suitable habitat is available onsite. California Brown Pelican, previously a special status species, was delisted in 2009; however, is included in the USFWS quad list for the site. It has very limited potential to occur at the project site. Action Area Outside the Project Site Two tidal marsh bird species, California black rail and California clapper rail, have potential to occur within the Project site once restoration is implemented. Currently the Project site does not currently contain suitable habitat for these species (Wetlands and Water Resources 2005b). However, there is suitable habitat in tidal marsh along Tolay Creek and the northern part of San Pablo Bay within the Action Area. The salt and freshwater marshes in the Action area currently provide marginally suitable habitat for saltmarsh common yellowthroat (Wetlands and Water Resources 2005b). Saltmarsh harvest mouse is present in pickleweed-dominated tidal salt marsh adjacent to the Project site in the southern baylands within the Action area (Wetlands and Water Resources 2005b). It is not currently expected to occur in the Project site due to a lack of tidal marsh habitat. However, it may occur onsite in the future once a tidal marsh plain and associated pickleweed marsh is restored (Wetlands and Water Resources 2005b). Saltmarsh harvest mouse may occur in Sears Point Wetland and Watershed Restoration Project Final Environmental Impact Report/Environmental Impact Statement 3.5-23 April 2012
